Ok well the other day i go out side to rip some paint threw my trix. I get out there ad start ripping with my 12" CP barrel wiht a 689 bore with premium paint... good stuff... so i shoot some of that threw no problems. It was ball on ball. Then i decide ok ill try my empire kit. I pull that out using 689 bore becasue thats wut my cp was throw that on take 1 shot chop... clean the barrel it shoots but way inaccurate... take another shot.. chop... so i try 691 bore... 1st shot way inaccurate 2nd shot chop.. 3rd very inaccurate... so i thought maybe the guns acting up.. so i throw my CP barrel back on it and yet again it ball on ball... I find that this empire barrel kit is a POS!!!
